What modification can you suggest in the Hardy Schulze law?

Explanation

### Step-by-Step Solution:

1. **Understanding Hardy-Schulze Law**:
The Hardy-Schulze law states that the coagulation of colloidal solutions occurs when oppositely charged ions are introduced. The presence of these oppositely charged ions leads to the neutralization of the charges on the colloidal particles, resulting in coagulation.

2. **Identifying the Limitation**:
The original Hardy-Schulze law only considers the addition of oppositely charged ions to induce coagulation. It does not account for the potential use of entire solutions that carry opposite charges.
